Belt heat treatment producing technology for solid electrolyte aluminum electrolytic capacitor

Abstract

The invention discloses a belt heat treatment producing technology for solid electrolyte aluminum electrolytic capacitor, a positive electrode guide pin is riveted on an anode foil, a negative electrode guide pin is riveted on a cathode foil; a winding machine is used for winding more cathode foil; the cathode foil covers the whole core bag and the high temperature adhesive tape is used for surrounding, clinging and fixing; the glue cover for sealing action is mounted on the core bag; the core bag is soaked in the formation liquid for repairing operation and taken out and absorbed with the redundant water; the processed core bag is processed on carbonization treatment; the soaking treatment and carbonization treatment for the core bag are repeated; the core bag is soaked in the formation liquid for repairing operation and cleaned in the deionized water after the formation treatment, the specific resistance of the water is greater than 2M; the monomer is soaked in the oxidizing agent, polymerized, thermal treated and packed in the aluminum shell, the opening is sealed and the aging treatment is executed for forming the finished product. After polymerizing the core bag, the high temperature treatment is executed, a abundant of impurity is volatilized for hydrolyzing and producing the sulfonic acid, the oxidation film of the core bag is broken, the whole capacitor is corroded and the service life is reduced.

Description

technical field [0001] The invention relates to the technical field of preparation of electrolytic capacitors, in particular to a method for manufacturing solid electrolyte aluminum electrolytic capacitors. Background technique [0002] The replacement products of traditional liquid capacitors for solid capacitor operation have their unique and excellent characteristics. At present, they are all used in the production process. The positive guide pin is riveted on the anode foil, and the negative guide pin is riveted on the cathode foil; Machine winding, more rolls of cathode foil, let the cathode foil wrap the entire core package, and then wrap around it with high-temperature adhesive tape to fix it tightly; install the sealing rubber cover on the core package; immerse the core package in the chemical solution for repairing, After taking it out, absorb the excess water; carry out carbonization treatment on the repaired core bag; repeat the immersion and carbonization of the ...

Problems solved by technology

During the use of the products produced in this way, it is found that some impurities will volatilize after high temperature is generated, and the volatilized substances will produce xanthic acid, which has a corrosive effect on the oxide film of the capacitor, which greatly reduces the service life of the product
